With "dual carbon" goals becoming a national strategy, China's manufacturing industry is undergoing a profound green transformation. As a traditional major emitter, the coatings industry faces an inevitable trend towards industrial restructuring and environmental upgrades. With increasingly stringent environmental policies and a continuously rising market demand for green products, the "solvent-free" process is accelerating. Industry forecasts predict that by 2025. environmentally friendly coatings will account for 70% of total coating production. This trend presents both transformation pressures and significant opportunities for technological innovation and industrial upgrading for coating companies. Powder coatings, with their outstanding environmental advantages, are becoming a core force in this transformation.
"The core of promoting carbon neutrality lies in reducing emissions during the production process, and reducing the carbon footprint at the source through product technology innovation and structural adjustments." This view has become an industry consensus. Coating giants such as AkzoNobel, PPG, Nippon Paint, Hempel, and SKSHU Paint have all listed it as a core measure in their respective carbon reduction plans. Against this industry backdrop, the powder coating industry, with its more significant environmental advantages, has ushered in a golden age of development, but it also faces increasingly fierce market competition. Meanwhile, the accelerated pace of technological innovation and intelligent manufacturing has placed higher demands on companies' clean production capabilities. Small enterprises with incomplete qualifications, weak foundations, and "dirty and chaotic" production environments are gradually being eliminated under the dual pressure of environmental inspections and market competition. Enterprises with core technologies and a commitment to green production, on the other hand, are seizing market opportunities with their product advantages. The key to powder coating's success lies in its inherent environmental protection genes: the spraying process is energy-saving and environmentally friendly, easier to automate, and compared to traditional solvent-based coating systems, it can reduce carbon emissions by 10%-55%, perfectly meeting the industry's development needs under the dual-carbon goals.
Among the many application areas of powder coatings, MDF (medium-density fiberboard) powder coating technology has become a key innovation direction promoted by the industry due to its outstanding application advantages. This technology not only addresses the environmental pain points of traditional MDF coating but also demonstrates unique value in multiple dimensions, including raw material supply, production efficiency, and product experience, providing a practical path for the green transformation of the coatings industry.
MDF powder coating uses artificial wood as its substrate, with widely available and recyclable raw materials. It does not rely on natural solid wood resources, protecting the ecological environment and ensuring a long-term, stable supply of raw materials, laying the foundation for large-scale industrial development.
MDF powder coating technology is easily compatible with automated production lines. The entire process, from spraying to curing, can be precisely controlled, significantly reducing manual labor. This not only lowers labor costs but also avoids quality fluctuations caused by human operation, improving product consistency and aligning with the development trend of intelligent manufacturing.
Compared to traditional paint coating, MDF powder coating produces no waste gas, wastewater, or waste residue during production. It eliminates the need for substantial environmental remediation costs, reducing the environmental burden on businesses and creating a healthier working environment for operators. It is a truly green production technology.
Products coated with MDF powder have zero VOCs and zero benzene emissions. Formaldehyde content is far below national standards, even reaching undetectable levels. This characteristic perfectly meets consumers' demands for healthy homes and green products, providing a safer choice for the end market.
Through diverse post-processing techniques, MDF powder coatings can achieve rich colors, textures, and surface finishes. Whether it's simple solid colors, natural wood grain, or special texture effects, they can be accurately presented, satisfying today's consumers' pursuit of personalized and diverse products. To achieve a revolutionary breakthrough in MDF powder coating technology, the first step in this long journey is to select the optimal core raw material – polyester resin. As the film-forming substrate for powder coatings, the performance of the resin directly determines the environmental friendliness, stability, and application efficiency of the coating. Therefore, the research and application of high-performance resins has become crucial for upgrading MDF powder coating technology.
On the track of innovation in environmentally friendly new materials, Hong Kong Standard Group Limited has always adhered to its mission of "making coating a green industry," continuously deepening its technological research and development, and injecting strong momentum into the low-carbon transformation of the coating industry. Addressing the core needs of MDF powder coating, Hong Kong Standard Group's low-temperature curing polyester resin, with its numerous innovative advantages, has become the focus of industry attention. The most significant breakthrough of this low-temperature curing polyester resin lies in its substantial reduction of the curing temperature of MDF powder coatings – lowering the traditional curing temperature from 190℃-200℃ to 120℃-140℃. This temperature reduction directly leads to a 20%–30% decrease in energy consumption, helping coating companies reduce carbon emissions at the source of production and steadily advance towards achieving their "zero" carbon goals. In the current climate of continuously rising energy costs and increasing dual-carbon pressures, this advantage brings significant economic and environmental benefits to companies. Meanwhile, this resin also features highly efficient curing. Compared to "standard" MDF powder coatings, coatings using this low-temperature curing resin can cure at the same curing temperature with a 25% faster curing speed. This means that without affecting coating performance and quality, production efficiency is significantly improved, allowing companies to complete production and delivery in a shorter time, saving time and costs, achieving cost reduction and efficiency improvement, and providing strong support for large-scale production. Furthermore, Hong Kong Standard Group's low-temperature curing polyester resin innovatively employs degassing technology. MDF substrates themselves have porous characteristics; during the curing process of traditional resins, the gas inside the substrate is difficult to release quickly, easily leading to defects such as pores and pinholes on the coating surface. This degassing technology helps gases escape smoothly from porous substrates, effectively preventing surface defects and resulting in a smoother, denser coating. Simultaneously, the resin offers excellent coverage and high coating completion, significantly reducing rework rates and bringing the scrap rate close to zero, further helping companies control costs and enhance competitiveness. It's worth noting that this low-temperature curing polyester resin is also easy to apply and offers a rich variety of colors. It is compatible with various pigments and additives, enabling the production of MDF powder coatings with diverse textures and colors, flexibly adapting to various application scenarios, including home furnishings, office furniture, and decorative building materials.
As a leader in the field of low-temperature curing resins, Hong Kong Standard Group Limited has not rested on its laurels. Looking to the future, the company will continue to focus on the research and innovation of circular economy products, constantly expanding product categories, optimizing product performance, and helping more coating companies accelerate the realization of low-carbon and energy-saving materials and production processes.
